Issuing Committee
E-31 Aircraft Eng Gas and Particulate Emissions Measurement
E-31 Committee was formed to develop and maintain cognizance of standards for measurement of emissions from aircraft powerplants and to promote a rational and uniform approach to the measurement of emissions form aircraft engines and combustion systems to support the practical assessment of the industry.
The E-31 Committee, in its operation uses an Executive Committee, Membership Panel, Subcommittees and working technical panels as required to achieve its objectives.Reference

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
